When using enriched air, Suunto Vyper can be programmed for nitrox mixtures between 21% and 50% oxygen

  You can also adjust oxygen partial pressure between 1.2 and 1.6 bar. In Gauge mode, it can also be used as a depth gauge and timer with profile memory.

Though lightweight and small, Suunto Vyper features a large screen, which is inclined toward you for easier readability. The high-definition electro-luminescent display can be adjusted to be on from 5 to 30 seconds and lights up automatically whenever an important alarm is activated. Suunto Vyper can be worn as a wrist unit with a protective boot, or mounted on a two or three-gauge console.

Using the Suunto RGBM algorithm, Suunto Vyper enables continuous decompression for optimal ascent time. The clear electro-luminescent backlight is activated automatically when dive alarms are given, making the dive parameters clearly visible and legible.

You can test upcoming dives and view no-decompression and decompression time data for different depths before getting in the water with the built-in dive simulator. When the dive is over, use optional Suunto Dive Manager PC software to transfer your dive data to your computer for further analysis and to maintain a detailed logbook featuring graphical representation of all your dives.
